Customer Reviews for Solar Powered Attic Fan Professional Series

The SunFan® Professional Series Solar Powered Attic Fan #9915TR is designed for shingle roofs only. For tile roofs, slate roofs, flat roofs, gable/static vents, and crawlspace ventilation, please consider the All Purpose Ventilator #1015APV, which is also available at Costco.com. New for 2013 - Black solar panel for improved camouflaged appearance. The award winning Sunfan® Solar Attic Fan #9915TR is our most powerful and efficient model yet, ventilating up to 1900 square feet of attic space with a single fan, requiring fewer fans to properly ventilate your attic space. The new, patent pending, Smooth-Air Deflector design in the shroud of the fan enhances the efficiency of air flow, resulting in increased ventilation performance by up to 30% over previous models – powered entirely by free and abundant solar energy. The SunFan® Solar Attic Fan 9915TR effectively reduces attic heat buildup in the summer months and moisture in the winter months. In the summer, your attic can easily reach temperatures of 160˚F, resulting in a battle between the attic heat and your air conditioner. With 43% of air conditioning design load based on high attic temperatures frequently reaching 160˚F, reducing attic heat also reduces air conditioning run-time. In the winter months, the building materials in your attic can absorb up to 28 gallons of moisture, contributing to mold and mildew growth. Moisture migrates into the attic space from daily activities such as running the dishwasher, showers and cooking. Additionally, warm attic air meeting the cooler temperatures of the roofing materials creates condensation, which drips onto the attic insulation causing it to lose its effectiveness. Warm attics in winter also contribute to ice damming as the snow melts on the roof and re-freezes at the eaves, causing water to accumulate and saturate the building materials. Extend the run-time of the SunFan® 9915TR into the evening by purchasing the innovative new Solar Controller. With the Solar Controller, you have the ability to monitor the temperature and humidity levels of the attic space as well as the operating status of your fan. By choosing to connect the Solar Controller to house power, the SunFan® 9915TR will continue operating even when solar power is not available.
